How do I convert this section of C++ code into Lisp using Lisp lists. I don't really need to show it but I have a C++ vector<int>I converted into lisp using CFFI. I converted the vector<int> filled with 5 numbers ,to a Lisp List.

Here is the final Lisp list:

(1 2 3 4 5)

I would like you to hopefully ignore what I said previously and pretend that I'm just starting out with the previously mentioned Lisp list and know I need to operate on it precisely as below so it will fit into the other C++ code I'm converting to Lisp. can you kind gentleman possible show my the exact Lisp equivelant of the below statement, operating on this exact list (1 2 3 4 5). Thanks in advance for any help on this.
